Unless you place every individual
In a bubble for months at a time.
The mathematical potential for rate of increase works both ways. If you consider the inverse proportionality of the natural logarithm then you understand the massive efforts at isolation are effective up until just under three contacts per person. After that the exponential rate of decrease flat lines. What does this mean? It means that anyone who is contagious who has been in contact with at least four people has completely defeated the idea of quarantine. I'm guessing that's just about everyone who's caught the virus.
At this point the quarantine becomes simply a feel good measure that will have no actual results on the rate of contagion. The only real way to combat the spread is to develop an effective vaccine.

I agree. Because of the lack of available testing we have no idea how far this has spread already.
Incorrect;
Any lab can test for this virus. The base COVID test kit can tell the presence of the virus as can any microbiologist looking at the slides. It is the RNA sequence that identifies the strain of virus in question and that takes a day or two to test for.
The rate this thing is mutating at makes specific strain identification hard. Simply knowing if your infected is rather simple and available at any basic hospital lab. In fact they test you for infection before they order further testing to stop wasting critical laboratory time.
